To aZZ whom it may concern/.-

Be it known that I, OTTO SoHiiLER, manufacturer, residing at Thurmstrasse 70, Berlin, N. W., Empire of Germany, have invented certain new and useful Improvements in Elevators and I do hereby declare the following to beafull, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and use it, reference being had to the accompanyingdrawings, which form partof this specification.

My invention relates to an elevator having an endless series of buckets.

The apparatus comprisesasuspended frame or arm secured to a carriage traveling'in a longitudinal direction, around which frame passes the endless chain, band, or the like, carrying the series of buckets. ,The said frame is preferably constructed with capability of being turned, so that it can be set at any desired angle to the vertical, and therefore reach down more or less near to the ground, as required, whereby the material, such as pit-coal and the like, may be elevated even from quite low heaps. The carriage is capable of being traveled backward and forward horizontally on its rails. which serve to support the wheels or rollers of the buckets on advance of the carriage are laterally displaced, so as not to obstruct the path of the wheels of the buckets in their motion around the pendent frame. For this reason the rails are constructed so that they can be moved. They may consist of separate movable members or of a wire rope, so that a section or portion of the track may be removed from' its normal course. The regular rails are then replaced by bridging-over rails secured to the carriage. The latter automatically controls the proper lateral oscillations of the sections of the rails (or corresponding part of the wire rope) by the aid of a guide-rail.

My invention is illustrated in the annexed drawings, in which-- Figure 1 is a side elevation, and Fig. 2 a front elevation, of the elevator. Fig. 3 illustrates one manner of arranging the rails in independent sections. Fig. 4 illustrates an arrangement of coupled rail-sections. Fig. 5 illustrates the use of a wire rope as a rail.

Me of motion in a transverse direction.

The rails a is the main framework from which the.

elevator is suspended and which may be capa- This framework carries the rails 12 b for the carriage c, from which latter is suspended, in the manner of a pendulum, the arm (Z, around which the bucket chain or rope passes. The buckets f are provided with wheels'or rollers running on the rails g h of the framework a. The carriage c itself, together with the suspended'arm d, can travel in a longitudinal direction. The rails which support the bucket-wheels are laterally displaced at that place where the carriage c, with arm (1, stands. For this purpose the rails g are constructed of separate sections or members or are composed of wire rope of sufficient strength, as shown, respectively, in Figs. 3, 4:, and 5. The sections of the rails (or the parts of the wire rope) are automatically displaced or bent by the carriage. At each end the carriage is provided with a bridge-over rail 6, of such length that it projects beyond the displaced section or portion of the rails g-and rests in front upon the adjacent sections of the latter rails. The rails 6 thus entirely bridge over those portions of the rails g which are displaced and serve to carry the bucket-wheels which run upon them.

The rails 9 rest upon the rocking'arms m m, secured to the frame a. One of each pair of these arms m is provided with a lever n, Fig. 2, rocking with it and carrying a roller Z. The lever n is of such form that its roller Z can run upon a guide-rail 70, carried by the carriage c. The extremities of the rail it project at either end of the carriage and are bent down to receive the rollers Z. To prevent the. rollers Z running off the rails is, the latter may be of channel section. The roller 1 travels along the rail 10 and by reason of the curved ends of the latter causes motion of the arms, and therefore of the corresponding rail-sections 9. On leaving the rail is the roller Z, and therefore the arms m, again return to the initial position. The sections of the rail g again close. running around the arm at elevates the material the carriage 0 travels on its rails, whereupon the rail 76 operates below the next roller Z on the arm 'n,thus displacing the corresponding rail-sections g. The rails e bridge over As the portion of the bucket-chain the gaps thus caused in the rails g and present a tread for the bucket-wheels. By this means the motion of the buckets around the arm 01 is nowhere obstructed by the rails g, whatever the position of the carriage e on the frame a.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An elevator comprising a main framework, a carriage running on the same, a frame pendent from said carriage, an endless series of wheeled buckets traveling around said pendent frame, rails for the bucket-wheels, carried by the main framework, and means whereby said rails can be laterally displaced by the carriage at the place where it stands, to admit of free ascent and descent of the buckets, all substantially as described.

2. An elevator comprising a main framework, a carriage running on the same, a frame pendent from said carriage, an endless series of Wheeled buckets traveling around said pendent frame rails for the bucket-wheels, pairs of jointed rocking arms supporting said rails and carried by the main framework, levers rocking with said arms, rollers at the end of said levers and a guide-rail carried by the carriage and traveled over by said rollers, constructed in such manner that as the rollers travel upon it, the arms and levers are rocked thus laterally displacing the bucket-rails at the place where the carriage stands, substantially as and for the purposes set forth.

3. An elevator comprising a main frame- Work, acarriage running on the same, a frame pendent from said carriage, and endless series of wheeled buckets traveling around said pendent frame, rails for the bucket-wheels, pairs of jointed rocking arms supporting said rails and carried by the main framework, levers rocking with said arms, rollers at the end of said levers, a guide-rail carried by the carriage and traveled over by said rollers, constructed in such manner that as the rollers travel upon it, the arms and levers are rocked, thus laterally displacing the bucket-rails at the place where the carriage stands, and rails carried by the carriage and bridging over the naps caused by the said displacement of the bucket-rails, so that the buckets can travel up and down uninterruptedly, substantially as described.

In witness whereof I have hereunto signed my name, this 28th day of April, 1902, in the presence of two subscribing witnesses.

OTTO SOHULER.
